I don't like those apples.
I always have questioned the rule about the capability of the pilot to fly an airplane that is capable of 150 mph, when the plane intended for the pulse jet won't go over 100 mph.
Another one I don't agree with is the requirement of a rudder. WHAT FOR? This type of plane needs no rudder at all.
I have a set up with a Delta Vortex with a Dynajet.
